SMOKE-CONSUMER.

Specification of Letters Patent. Patented Sept. 20, 1921.

Application filed October 6, 1919 Serial No. 328,829.

To all whom it may concern:

locomotive during the running of the en gine or when standing stationary and it con sists essentially of the arrangement and construction of parts as hereinafter more particularly explained.

Figure 1, is a side elevation of a locomo-- tive body partially broken away and in section to exhibit the interior construction thereof and my device applied thereto.

Fig. 2, is a plan sectional detail through the steam inlet manifold.

Fig. 3, is an enlarged sectional detail through the fire door of the locomotive firev box. I

In the drawings like characters of reference indicate corresponding parts in the vafigures.

1 indicates the body of the locomotive, 2 the fire box, provided with the usual back arch 3, 4 the rear flue sheet, 5 the front flue sheet, and 6 the flues of the locomotive boiler. 7 is the locomotive stack and 8 the exhaust nozzle which is located beneath the stack in accordance with the usual practice.

9 is a fire door of the fire boxthe construction of which I will hereinafter describe.

10 is a steam dome which is located in proximity to the rear end of the engine body. 11 is a flange which extends around the fire door opening. 12 and 13 are fire doors which are of wing construction; a type which is commonly used in the construction of locomotives and which are hinged at the outside of the fire door 0 ening and contact one with the other at 14. Tn this construction a slight inter-space is left between the outer edge of the flange and wing of the fire door. 15 is a pipe which extends around the flange 11 so as to bridge the space between such flange and the fire door. 16 are a series of nozzles which extend from'the pipe 15 through the inter-space hereinbefore referred to.

17 are tubes which extendlongitudinally of the locomotive body at each side thereof andare located next to the body so as to be embedded within the insulating cover 18 with which the locomotive body is covered in accordance with the usual practice. The forward end of each tube 17 is provided with a funnel shaped mouth 20 throughwhich air is forced by 'the forward travel of the locomotive this air being carried longitudinally through the tube 17 to the pipe 15. The tube 17 is in close contact with that portion of the wall of the body of the-locomotive forming the boiler and such air is thereby heated as it is forced rearwardly into the pipe 15 and is injected in a heated state into the front of the fire box through the fire door opening.

21 is a steam manifold. 22 designates nipples secured in the back sheets of the fire box. 23 are small pipes extending from the manifold 21 through the nipples 22 the inner portions 24L of such pipes being inclined downward so as to direct the steam into the body of smoke as it passes around the upper edge of the arch 3. The manifold 21 is sup plied with steam from the steam dome 10 through the pipe 24 which is provided with a T 25. One arm of the T is connected by apipe 26 to the manifold 21. 27 is a valve by which the flow of steam of the manifold is controlled. 28 is a cover for the manifold provided to prevent the chilling of the steam passing into the interior of the firebox. 29 is a pipe which extends from the other arm of the T 25 such pipe passing to the outside of the engine body to a point in proximity to the nozzle 8. The end of the pipe 29 at the point where it extends to the nozzle 8 extends inwardly over such nozzle'and is provided with an upturned nozzle 30. 31 is a valve controlling the flow of steam to the nozzle 30.

When the engine is running the exhaust steam passes from the nozzle 8 through the stack 7 so as to create an up-draft in accordance with the usual practice. When the engine is standing stationary this up-draft is created by means of a jet of steam passing upwardly from the nozzle 30 through the center ofthe stack 7.

By my device it will be seen that the heated air and steam are carried separately into the fire box and do not co-mingle until they are brought into contact with the smoke particles. I find by this means that very much would otherwise be the case.

It will, of course, be understood that during the ordinary running of the engine, that is when the locomotive is traveling, the steam valve 31 would be closed and such valve is only opened to create an artificial draft when the engine is stationary have formed the wings12 and 13 of the fire heated boiler wall and having an open for- In order to prevent the draft passing from the perforated fire door chilling the fire, I

door in a way which I will now describe.

vEach wing 12 and.13 is formed hollow the outer wall of each wing being provided with perforations 32 and the inner wall with perforations 33. 34 is a bafilePlate which is located in the hollow wing between the perforations 32 and 33 and thereby prevents the direct draft of cold air passing throughthe fi're door in the fire box over the fire. The cold air passing through the perforations 32 I strikes the heated plate 34: and as it passes around such plate to the perforations 33 becomes heated to a sufficient extent to overcome its chilling effect.

From this description it will be seen that I have devised a Very simple form of smoke consumer which will be found very efiicient in operation by means ofthe steam and air being separately fed to the point of utilization and as they are so fed being heated so that they are supplied in an absolutely dry state.

The air pipe 17 may be provided with a controlling valve 17 in order to regulate the air supply flowing into the fire box of the 10- therein provided with'the usual fire door opening and fire doors, of a tube extending longitudinally of the locomotiveboiler and embedded in the insulated-cover next to the ward directed mouth at its front end and extending at its rear end to the fire door opening, a nozzled pipeconnected to the inner end of the aforesaid-tube the nozzles of which are directed into the fire door opening, a pipe leading from the'steam dome,"a manifold located above the fire'door, a series of pipes extending" from the manifold through the wall' of the fire box and having downwardly directed inner ends adaptedto 3 direct the steam over the-fire bed, a covering. for themanifoldyandia controlling valve for the steam dome pipe.
